Vintage Mars Bar Discovery: A Glimpse into shrinkflation

A chocolate bar from the early 90s has surfaced during a residential clean-out, sparking a viral conversation about how product sizes have diminished over time—a phenomenon known as shrinkflation.

The Discovery in Scunthorpe

While performing a house clearance in Scunthorpe, Victoria Gordon, the proprietor of the cleaning company Pocket Rockets, stumbled upon a Mars Bar with a best-before date marking it as a relic from 1991.

Gordon noted that the item immediately caught her eye due to its unusual dimensions. Speaking with BBC Radio Lincolnshire, she explained:

"We were clearing out a hoarder's house and everything we were rooting through was decades old. This Mars Bar stood out to me because as I picked it up it was nearly the whole length of my hand. I was like, 'Wow, look at the size of that!'"

Size Comparison Analysis

The difference in mass between the vintage find and a contemporary version is stark.

Using basic mathematics to find the difference: Δweight=62.5g−40g=22.5g\Delta \text{weight} = 62.5\text{g} - 40\text{g} = 22.5\text{g}Δweight=62.5g−40g=22.5g

The Corporate Perspective

When contacted for a statement, a representative from Mars explained that changes in the product's physical footprint are not accidental but are based on various operational and market factors.

"Over the last 35 years, we have made a number of updates to our bar sizes and pack formats to reflect consumer demand, alongside considering wider external factors such as manufacturing costs and the price of cocoa."

  • Keep it as a curiosity
